I was just thinking after reading the comments on the cycle shelter story in the Hootsmon, which had thread drift that this place would be proud of, that the differing views of what to do after someone is injured by a bike or car are indicative of their relative perceived importance as well.
One person hit by a bike years ago on Porty Prom and 'No Cycling' signs go up. I've yet to hear of a single road that was closed completely to cars simply because a pedestrian was struck by a car (I guess it wouldn't leave many places to drive).
Also, when there's an incident involving a bike then, naturally, the public response is that cyclists should be stopped, or controlled, or run over, or taxed. In many many incidents involving cars the immediate response is "Well that's a dangerous piece of road."
I propose that all road users are on equal footing!
